What is the reason why the Passat Lingyu sunroof stops halfway when closing?

[DelVincent]

Passat Lingyu sunroof stops halfway when closing due to foreign objects in the sunroof track or lack of lubrication on the track. Foreign objects in the sunroof track: Foreign objects in the sunroof track can cause the car sunroof to fail to close and bounce back. In such cases, first check the track and remove any foreign objects if present. Lack of lubrication on the track: If the track lacks lubricant, causing excessive resistance, the sunroof's anti-pinch function will activate, causing the sunroof to bounce back. In this case, simply add lubricant to the track. After cleaning the track and adding lubricant, if the sunroof still does not close properly, you can perform an initialization operation on the sunroof.
